has estimates, actual, and revisions (no timestamps....but has the schedule)Some items are missing (for example, it has the US 10yr auction...but not the US 30yr bond auction)...but most macro data is there.

Also, for many releases, there is the headline data....but also many sub line items (for example, in the NFP jobs report, many people look to the household survey, which does not show up in the headlines...you have to look into the report details on the bls.gov website to see the details (which all the banking economists do when the report is released, and then they send out commentary talking about the "internals". its would be helpful if these reports were in an easily accessible format so that we could feed them into a machine learning algo...but most often that is not the case.).

Macrobond.com is a much better product, but can be pricey for the retail hobbyist.

Macrobond looks interesting, though i am still waiting for the sample to check it out. Supposedly, Trading Economics dataset also has all of the key economic numbers, with timestamps and stuff like that included. So far, though, nothing looks any better than Bloomberg for my purposes.

I don't interest myself in 'why?'. I think more often in terms of 'when?'...sometimes 'where?'. And always how much?'
